Definitions

  • the present invention relates to a vent for the climate-control air of motor vehicles, and more precisely to an air vent that has the characteristics stated in the following claims.
  • the air vent according to the invention can be installed in any place of the dashboard or console of a motor vehicle and is also suitable for lateral installations, i.e. at the two ends of said dashboard.
  • the air vent according to the present invention comprises a diffuser body that contains a flow concentration duct having decreasing cross-sections.
  • Both said diffuser and said concentrator which can have any kind of cross-section, end at a grille the thickness whereof is approximately 5-30% of the shorter side of the outlet section of the concentrator.
  • the grille has air passage channels that preferably have a conical axial shape; with respect to the direction of the air stream, said channels diverge in the diffusion portion of the grille that closes the outlet section of the diffuser and converge in the concentration portion of the grille that closes the outlet section of the concentrator.
  • a valve unit with a pair of valve elements, is provided so as to separately close or reduce the inlet sections of the diffuser and respectively of the concentrator, and an actuation means, equipped with a pair of cams that cooperate with respective pins for moving the elements of the valve unit, is provided in order to independently move said elements by means of a single knob that protrudes from a base arranged to the side of the grille.
  • the reference numeral 10 designates a hollow diffuser body that extends and flares out from a manifold 11 meant to receive the feed duct (not shown) of the climate-control air.
  • the diffuser body 10 which delimits a diffusion chamber 10c that has any kind of cross-section, or a quadrangular or a circular one, is internally provided with a flow concentration duct 12 the cross-sections of which decrease along the flow direction; said cross-sections also have a generic profile, or a quadrangular or a circular one, and therefore the duct 12 is substantially frustum- or pyramid-shaped.
  • the diffuser body 10 and the concentration duct 12 are preferably formed separately, advantageously using thermoplastic material, and are rigidly coupled to each other with conventional connection means, advantageously by welding or, alternatively, by means of an adhesive and/or by virtue of snap-together elements (not shown).
  • Both-said diffuser body 10 and said concentration duct 12 have respective outlet sections 10a,12a at which there is a grille 13 the thickness whereof is approximately 5-30% of the shorter side of the outlet section 12a of the concentrator 12.
  • the grille 13 is divided into two portions 13a,13b respectively for diffusion and concentration; the first one faces the outlet section 10a of the diffuser 10 and the second one faces the outlet section 12a of the concentrator 12.
  • Said grille portions have respective series of air passage channels 14,15 that preferably have a conical axial shape but have different orientations with respect to the direction of the flow.
  • the channels 14 of the diffusion portion 13a of the grille advantageously diverge with respect to the direction of the flow F, whereas the channels 15 of the concentration portion 13b of the grille advantageously converge.
  • the cross-section profile of the channels 14,15 can be entirely generic; it is preferably circular. It is also possible to form the channels 14,15 with a cylindrical axial profile and to orientate the axis of said channels, whether conical or cylindrical, at generic angles with respect to the normal to the plane of tangency of the grille in the point being considered.
  • a pollen filter 16 is advantageously arranged between the grille 13 and the outlet sections 10a and 12a of the diffuser and respectively of the concentrator and can be removed for replacement; in particular, said filter can be inserted and extracted through a slot 10b provided on the body 10 at the respective outlet section 10a (figure 6).
  • valve unit 17 is provided in order to separately close or reduce the inlet sections of the diffuser 10 and respectively of the concentrator 12.
  • Figures 5, 5a and 5b show that the valve unit 17 is formed by two valve elements 17a,17b including respective panels 170,171 that are mutually connected, so that they can perform a relative angular movement, by a film hinge 172 (figure 5b); the valve unit 17 is also made of thermoplastic material.
  • Respective riveted counterpanels 170',171' cooperate with the panels 170,171; the panels and the counterpanels are suitable to clamp in a sandwich-like manner a flexible gasket 18 that runs along the perimeter of the valve elements 17a,17b.
  • the panel 170 also has two pivots 19 suitable to cooperate with respective holes 19a provided in the diffuser body 10 (figure 4) to hinge the entire valve unit 17 to said body.
  • Both panels 170,171 furthermore have rigid sectors 20, 21 (figure 5) for supporting corresponding actuation pins 22 and 23 respectively, which protrude outside the body 10 by passing in a circular slot 24 provided on a side wall of said body and arranged concentrically with respect to the corresponding hole 19a.
  • An actuation means that cooperates with the actuation pins 22,23, is provided in order to independently move the valve elements 17a,17b by means of a single knob 26 that protrudes from a base 27 located to the side of the grille 13.
  • the actuation means 25 comprises an oscillating plate 28 that has a pivot 29 rotatably accommodated in a corresponding hole 29' of the diffuser body 10; the knob 26 is rigidly coupled to one end of said plate and a transmission head T is rigidly coupled to the other end of said plate.
  • Cam-shaped slots 30,31 are formed in the head T and cooperate with the actuation pins 22,23 respectively.
  • the slots 30,31 have respective central parallel portions that are shaped like a circular arc the center of curvature whereof is located on the axis of the pivot 29 and are accordingly ineffective in terms of the angular movement of the respective valve elements 17a,17b; said slots furthermore have profiled opposite end portions 30a,31a so as to produce, by engagement with the respective pins 22, 23, the oscillation of the valve elements 17a and 17b respectively.
  • valve element 17b is rotated in the clockwise direction shown by the arrow so that, as clearly shown, the two valve elements fully close both inlet sections of the diffuser 10 and of the concentrator 12.
  • valve element 17b In the configuration shown in figure 2, which is obtained by moving the knob 26 into the angular position FC (concentrated flow), the valve element 17b, again by virtue of the engagement of the pin 23 with the end portion 31a of the slot 31, is rotated clockwise as indicated by the arrow and frees the inlet section of the concentration duct 12.
  • the angular positions of the knob 26, that are intermediate with respect to those described above, are matched by respective partial closures of the concentration duct 12 and/or of the diffuser 10.
